Abstract
A memory device, such an MRAM device, includes self-healing reference bits () associated with a set of array bits (). The memory performs an error detection step (e.g., using an error-correction coding (ECC) algorithm, to detect the presence of a set of errors within the data bits. One of the reference bits () is toggled to a different state if an error count is greater than a predetermined threshold. If the set of errors remains unchanged when subsequently read, the reference bit () is toggled back to its original state.
